Perovskite oxides ABO3 offer a vast playground for applications and basic research. Especially multifunctionality is a frequently targeted aim, since the replacement of the A and/or B sublattice ions easily changes the properties of the system. Here we concentrate on the perovskite EuTiO3 (ETO) which was ignored by the scientific community for a long time. We review recent results on it and show that...
Specific heat and magnetization measurements demonstrate that the antiferromagnetic (AFM) phase transition at TN = 5.7 K of EuTiO3 is rapidly suppressed with Sr doping in EuxSr1−xTiO3. Close to x = 0.25, TN = 0 K and AFM order vanishes. Above this critical concentration a finite transition temperature to an AFM phase is observed. The exchange couplings are derived as a function of x and the...
